STOVE FOR HEATING PURPOSES.

SPECIFICATION forming part of Letters P atent No. 663,380, datedDecember 4, 1900.

Application filed February 5. 190i)r Serial No. 4,072. (No model.)

To all w'w'nz it 77u03/ concern:

Be it known that l, VILLIAM YOULTEN, a subject of the Queen of GreatBritain and Ireland, residing at 159 Victoria streetVestminster, London,England, have invented lmprovements in Stoves for Heating Purposes, (forwhich l have made application for a patent in Great Britain, No. 14,292,dated the llth day of July, 1899,) of which the following is aspecification.

The object of this invention is to provide a stove which shallefficiently heat an apartment by the consumption either of gas or ofcoal, wood, or other fuel, as may prove most desirable, having regard tothe circumstances attending its use'for warming purposes-6. g. thetemperature or length of time on any given day or night during which itmay be desired to keep the fire burning. According to one way ofeffecting this object I construct the stove, which may be of any desiredshape, in such a way that it may be readily rotated about a verticalaxis by means of suitablyplaced t-op and bottom pivots, as hereinafterdescribed.

Reference is had to the accompanying drawings,in which the same partsare designated by the same characters of reference throughout theseveral views.

Figure l represents a central vertical section of a stove constructedaccording to my invention. Fig. 2 represents a horizontal section of thesame, taken on the line 2 2 of Fig. l. Fig. 3 represents a horizontalsection through the lower part of the fireplace and the gaspipe, showingthe base, frame, and lower pivot-pin in plan. Fig. 4 represents ahorizontal section taken on the line 4 4 through the upper part of thefireplace, showing the top of the stove in plan. Fig. 5 represents acentral vertical section of another form of stove with my inventionapplied thereto; and Fig. 6 represents a horizontal section of the same,taken on the line 8 S of Fig. 7.

On a suitable base-plate d I mount the sto ve so as to rotate about avertical axis by providing strong bottom and top pivots b and c. Thebottom pivot b, fitted in the base-plate a, I make hemispherical inshape at the top, so as to work in a strong cup-socket d. The top pivotc enters a soot guard-plate e., horizontally covering thechimney-opening', except for an aperture therein which affords a communication with the ilue g from either the gas or coal grate, ashereinafter referred to. The surroundings of the pivot c are protectedby a socket-coverf, screwed over the top of the pivot c through to theupper surface of the soot guard-plate e.

The stove is divided into two grat-es 7L and z', one of the grates,7t,being intended for coal or other fuel and the other, z', for gas. Thegassupply is taken preferably over or under the hearth to a pointadjoining the pivot b. It is then conveyed to an aperture m in thelatter. When the stove is in the position shown at Fig. l, where thestove is represented as it would appear when the grate h for coal orother fuel is facing the room, the aperture m comes opposite a hole lain the circular socket d, which hole lt communicates with the pipeleading to the Bunsen burner or burners n, intended for lighting thecoal or other fuel in the grate h. These burners are close under the baror bars o of the grate, the bars projecting sufficiently on either sideof the burners to prevent dust or ashes from entering such burners. zshows another hole in the circular socket d. When the stove is rotatedso that the gas ire faces the room, this hole e comes opposite theaperture m. Thus gas is supplied to the burners of the gas lire. y isthe bottom plate of the revolving stove.

Communication between the two grates and the flue is automaticallyeffected or prevented by providing in the soot guard-plate e an aperturep of a size snfcient to enable the smoke from the coal fire or the fumesfrom the gas-stove Lo ascend into the line g. In the top pivot-plate q,which is secured to the upper part of the revolving portion of thestove, two apertures r and s are formed, corresponding in size and formto that above referred to in the soot guard-plate e. These two aperturesare respectively placed directly over the coalgrate and the gas fire.Thus when the former faces the room the smoke-aperture r in the toppivot-plate q is immediately under the aperture p in the sootguard-plate e, thereby affording a direct communication for the smoke toascend into the flue g, while the aperture s for the emission of fumesfrom the gas-grate is beneath the soot guard-plate e, thus preventingany communication between the gas- IOO stove and the Iiue andconsequently prevent-` ing a fall of soot or mortar into the gas-stove.When the positions of the stoves are reversed, the apertures above themare likewise reversed.

In order to prevent heat from the gas fire igniting the coal in thecoal-grate when this latter is not in use, I provide a fire-claypartition #between the two stoves, in the center of which partition is ahollow space which may be filled in with a thickness of asbestos orother material which is a non-conductor of heat.

I may provide sliding screens which draw ont of the wall to inclose thestove and act as blowers when required. These screens are not shown onthe drawings.

I hinge the cheeks' u, of the stove and form rabbets between them andthe rotating portion of the stove, so that no draft may pass around thestove. These hinged cheeksu may also be employed as screens when desiredby swinging them outward into the room. Even in this case no draft willpass; as the soot guard-plate prevents it.

I prefer to make the grate for coal or other uel larger and deeper thanthat for the gas Y By a few modifications of the details above describedthe stove can be as conveniently fitted in a casing to form a closestove, which usually stands wholly or partially clear of thechimney-opening or fireplace. Figs. 7 and 8 show my invention applied'toa stove of this description, Fig. 7 being a vertical section and Fig. 8a sectional plan taken on the line 8 8 of Fig. 7. In this case the wholestove rotates on the pivots b and c. l is a waterchamber provided withapertures 2 for the escape of steam. 3 represents columns for supportingthe upper portion of the stove.

What I claim, and desire to secure by Letters Patent, is-

1. In a stove, the combination with a structure comprising a grate forburning hard fuel,

a grate for burning gas, a partition between the two grates, a fluecommunicating with one of the said grates, and a bottom plate havinggas-pipes leading to each of the said grates, of a pivot-pin supportingsaid bottom plate, the structure being arranged to rotate upon the saidpivot-pin to bring one or the other of the said gratos intocommunication with the said flue, and means whereby the rotation oi' thegrates will cause the gas to be admitted to the grate which is incommunication with the Hue, substantially as described.

2. In a stove, the combination with a structure comprising a grate forburning hard fuel, a grate for burning gas, and a partition between thetwo grates; of pivot-pins supporting the said structure, a gas-vent inone of the said pivot-pins and means for conducting gas to the saidvent, a gas-pipe cominunicating with each of the said grates, andarranged to register with the said vent when that particular grate is inoperation, substantially as described.

3. In a stove, the combination with a structure comprisingagrate forburning hard fuel, a grate for burning gas, a partition between the twogrates, a top plate having openings therethrough for the escape of theproducts of combustion, and a bottom plate having gaspipes leading toeach of the said grates; of a pivot-pin supporting the top plate, apivot-pin having a gas-vent therethrough supporting the lower plate, thesaid structure, being arranged to rotate upon the said pivot-pins tobring one or the other of the grates to the front, and at the same timeto cause the gaspipe to that grate to register with the vent in thelower pivot-pin, and means for conducting gas to the said vent;substantially as described.
